To support face swapping, the Cameo project has two new modules called rects and trackers. The rects module contains functions for copying and swapping rectangles, with an optional mask to limit the copy or swap operation to particular pixels. The trackers module contains a class called FaceTracker, which adapts OpenCV's face detection functionality to an object-oriented style of programming.
As we have covered OpenCV's face detection functionality earlier in this chapter, and we have demonstrated an object-oriented programming style in previous chapters, we will not go into the FaceTracker implementation here. Instead, you may look at it in this book's repository.
Let's open cameo.py so that we can walk ...
